Quercus macrocarpa | Bay Area

Bur Oak has occasionally been grown in the California nursery industry. Here can be seen some large nursery stock growing the Bay Area. These trees are representative of genetics of trees originally grown in Missouri. Use of Bur Oak in California has been limited by susceptibility of many strains to powdery mildew, and other leaf diseases. These leaf diseases rarely impact the ability of the trees to grow, but do strongly impact their aesthetic performance. The trees pictured have proven susceptible, but the choice was made to simply limb the trees up to a height where the leaves are hard to see clearly. Otherwise, Bur Oak is a strong growing tree, and is considered quite attractive and interesting by those exposed to it.
